This question has more than likely been addressed in this forum before.
Whitch .32 is the most accurate and reliable? Pardini, Walther, Hammerli, or other.

Find a current production pistol or revolver (ongoing parts and service backup) that fits your hand (correct grip size,rake and style, trigger position location), where the balance and weight suits you and it meets all the ISSF rules, buy it and shoot.
Try as many guns on the range as you can, you will find the one you want.

I wouldn't pick a Hammerli myself, I don't like the carbon reinforced plastic frames which tend to crack.

Otherwise pick whichever suits you.

All being well and with good ammo any .32 ought to hold the x-ring.

Thanks.

The Pardini HP-in .32 Cal is pretty reliable and has been out there quite a while.

Not be too much of a self-promoter, I'm selling a Benelli MP90s right here in the Buy, Sell, Trade Forum. If you're in the US please take a look.
